S201, equipment adjust: after the step S103 of dry run completes, open the inlet valve of the outlet valve of cyclone dust collectors branch road, cyclone dust collectors branch road successively, close the valve I of malleation circulation line, start ultraviolet sterilization fluorescent tube;
S202, sterilizing and heavy seeds are separated: the fluidisation state pollen pini of high-speed circulating flowing enters cyclone dust collectors with air-flow, the impurity that proportion is larger is separated and is collected in bottom cyclone dust collectors under centrifugal action from fluidisation state material, pollen pini is then discharged through cyclone dust collectors blast pipe with air-flow, simultaneously, pollen pini cell is constantly random close to ultraviolet sterilization fluorescent tube, microorganism is subject to abundant Ultraviolet radiation and is killed, the content of microorganisms of a material is checked every 3 ~ 5 minutes, until content of microorganisms meets the requirement of GH/T1030-2004, close ultraviolet sterilization fluorescent tube,
S3, screening
S301, equipment adjust: the aperture regulating screen drum control valve in screen drum branch road is 5 ~ 35%, open the valve II of the inlet valve in screen drum branch road, malleation circulation line, close the control valve of the inlet valve of deduster branch road, cyclone dust collectors branch road, deduster branch road, the circulation canal internal circulation flow that pollen pini is formed at blower fan, malleation circulation line, screen drum branch road, negative-pressure cyclic pipeline with air-flow;
S302, screening: after fluidisation state material enters screen drum branch road, the screen cloth that the pollen pini being less than mesh size passes screen drum with air-flow realizes airflow screening;
S303, deslagging: after having sieved, open the residual cake valve of malleation circulation line, and close the inlet valve of screen drum branch road, the control valve of standard-sized sheet screen drum branch road, the oversize in equipment is discharged through residual cake valve with air-flow;
S304, shutdown: close blower fan and whole valve, cut off the electricity supply.
